Abstract: The present invention provides an emitting device that is applied to a communication product having a casing and a plurality of embedding portions installed at the casing. The emitting device comprises a plurality of emitting portions corresponding to the embedding portions respectively and a plurality of connecting portions, and each connecting portion is coupled between two adjacent emitting portions, and each emitting portion is embedded into each embedding portion and partially exposed from the casing, such that the integrated emitting device can reduce the level of complexity of the conventional assembling process.

Abstract: An assembly device applicable to assembling an isolation cover to a main body of a circuit board is provided. The main body and the isolation cover respectively have a plurality of first positioning portions and a plurality of second positioning portions corresponding to each other. The second positioning portions correspondingly pass through the first positioning portions, respectively. The assembly device includes a base, a press-fitting mechanism movably connected to the base, and a drive mechanism disposed at the base. The base has a supporting portion for disposing the isolation cover and the main body. The press-fitting mechanism has a press-fitting portion facing the supporting portion. The drive mechanism has a drive portion connected to the press-fitting mechanism, for driving the press-fitting mechanism to move towards the supporting portion of the base via the drive portion, so as to bend and fasten ends of the second positioning portions.

Abstract: The present invention provides a circuit board having an isolation cover and an assembling method thereof. The circuit board of the present invention comprises a main body and an isolation cover disposed on the circuit board main body. The main body and the isolation cover have a plurality of corresponding first and second positioning portions, and a ground portion is disposed on at least one side of each first positioning portion. The isolation cover is disposed on a first surface of the main body, and each second positioning portion passes through a second surface of the main body and each first positioning portion. An end of each second positioning portion is connected to each ground portion.

Abstract: The present invention provides a circuit board of a communication product and a manufacturing method thereof. The circuit board comprises a main body of a circuit board and an isolation cover. A surface of the main body of the circuit board has a power transistor, an insulating layer, a plurality of first openings disposed at intervals on the insulating layer and around the power transistor, and a plurality of soldering portions exposed from the first openings respectively. The isolation cover comprises a cover body and a plurality of second openings equidistantly opened on a lateral side of the cover body. The isolation cover is disposed on the surface of the main body of the circuit board, and is soldered to the soldering portions through a local spot soldering process.

Abstract: The prevent invention provides an activating and positioning method for an electronic device comprising at least a Global Navigation Satellite System (GNSS) receiver and a storage unit. The storage unit is utilized for storing a time file recording time information so that the time file can be obtained when activating the electronic device, and the time information recorded by the time file can be set as a current system time of the electronic device. Then, the activating and positioning method of the prevent invention activates the GNSS receiver to perform a positioning process according to the system time. Thus, the prevent invention can overcome disadvantages of the prior art which records system time by using hardware scheme.
